The yield of SIM according to the patterns was: (i) Regular microstructural pattern with tubular\/linear\/villous pattern 90.6% and with circular pattern 0%; and (ii) Absent microstructural pattern 98.9%. The sensitivity, specificity, positive and negative predictive values of the combination of regular microstructural pattern (tubular\/villous\/linear) and absent microstructural pattern to detect SIM were 100%, 78.8%, 93.5% and 100%, respectively.
